Abstract

The invention relates to a multi-functional hydrotalcite/polymer nano-composite additive for leather and a preparation method thereof. The dispersity of hydrotalcite in water is poor, and a polymer of the hydrotalcite is applied to a discoloring phenomenon produced by the leather. The preparation method utilizes acrylic acid, ammonium persulfate and allyl sulfonate to prepare a water-soluble polymer, the hydrotalcite is added to perform ultrasonic reaction, and the multi-functional hydrotalcite/polymer nano-composite additive is obtained. The multi-functional hydrotalcite/polymer nano-composite additive can reduce the environmental pollution caused by tanning effluent. In addition, a positively charged hydrotalcite plate layer is conducive to the absorption of anionic dyes, a fat-liquoring agent and other chemical materials during later retanning, dyeing and fat liquoring, and the quality of finished leather is guaranteed.
